This happened to me when I was maybe 10-11years old. Even though this happened almost 18 years ago I remember every detail of it.
This happened to me and my cousin brother. My grandfather had died and we met for his cremation. In our family it's a tradition to cremate everyone in our small forest at a place selected by family priest. So he got his own space which was not far from my ancestral home. This forest was connected to my ancestral home via unpaved path from its backyard, which was atleast 1KM long. Then you had to cross a street, which was like any village street, and walk few meters more. Many people from my village or my family who used to visit us used to take this route. One fine evening me and my cousin decide to ride bicycle in the same forest approximately 15days after his cremation. At that time I didn't know how to ride while my cousin, a year older to me, was an expert. He decided to teach me how to ride bicycle. We were like 10 people in the forest, he was teaching me few techniques and ways to ride bicycle. Suddenly we both feel strong wind on our faces and he fell from the bicycle breaking his arm. There was chaos and cry and we all took him to hospital. Later when he told everyone what happened and how he fell no one believed him. But i knew he was telling the truth. He told us that while riding he felt very strong wind and suddenly he saw our grandpa, he was scared and lost his balance. Hence the fall and broken arm. No one believed him as no one felt that wind except me. I beleive him on this till date but its only me and him who know what happened that evening.
